INPUT/OUTPUT FUNCTIONAL DESCRIPTION
Symbol
Type
Function
CK, CK
Input
Clock: CK and CK are differential clock inputs. CMD, ADD inputs are sampled on the crossing of the positive
edge of CK and negative edge of CK. Output (read) data is referenced to the crossings of CK and CK (both direc-
tions of crossing).
CKE
Input
Clock Enable: CKE HIGH activates, and CKE Low deactivates, internal clock signals and device input buffers
and output drivers. Taking CKE Low provides Precharge Power-Down and Self Refresh operation (all banks idle),
or Active Power-Down (row Active in any bank). CKE is synchronous for power down entry and exit, and for self
refresh entry. CKE is asynchronous for self refresh exit. CKE must be maintained high throughout read and write
accesses. Input buffers, excluding CK, CK and CKE are disabled during power-down. Input buffers, excluding
CKE, are disabled during self refresh.
CS
Input
Chip Select: All commands are masked when CS is registered HIGH. CS provides for external bank selection on
systems with multiple banks. CS is considered part of the command code.
RAS,
CAS,
WE
Input
Command Inputs: RAS, CAS and WE (along with CS) define the command being entered.
DM0
~DM3
Input
Input Data Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH
coincident with that input data during a Write access. DM is sampled on both edges of clock. Although DM pins
are input only, the DM loading matches the DQ and DQS loading.
BA0,
BA1
Input
Bank Address Inputs: BA0 and BA1 define to which bank an Active, Read, Write or Precharge command is
being applied. BA0 also determines if the mode register or extended mode register is to be accessed during a
MRS or EMRS cycle.
A0 -
A11
Input
Address Inputs: Provided the row address for Active commands and the column address and Auto Precharge bit
for Read/Write commands to select one location out of the memory array in the respective bank. A8 is sampled
during a Precharge command to determine whether the Precharge applies to one bank (A8 LOW) or all banks (A8
HIGH). If only one bank is to be precharged, the bank is selected by BA0, BA1. The address inputs also provide
the op-code during Mode Register Set commands.
DQ

Data Input/ Output: Bi-directional data bus.

input
Resistor connection pin for On-die termination.
The value of Resistor = 2 X (target value (Rterm) of termination resistance of DQ pin of each chip)
